Generator control system management methods

The product concept

Generator Controller (the Generator Controller), is the control center of the Generator, it command Generator to coordinated work, guarantee the Generator shall be carried out in accordance with the prescribed goals and steps to methodically operating and processing.Controller from the storage to take out a detailed instruction, analyzes what is specified by each instruction operation and location of the required data, then according to the results of the analysis to the generator control signal from the other part, the unified command complete instructions specified operating the generator.Generator automatic working process, in fact is the process of automatically execute a program, and program of each instruction is performed by the controller to the analysis, it is the main facility of the generator to realize "process control".

LXC6610 series power station automation controller used for a single diesel generating sets automation and monitoring system, using 32-bit microprocessor technology, the realization of generating set automatic starting/stopping, various parameters precision measurement, alarm, protection and the "three remote" function.Big screen LCD controller USES a (240 * 128 LCD) graphic display, under a page can show that almost all of the important parameters, dispense pages.At the same time can show Chinese, English and other languages, all parameters can be adjusted from the controller panel, also can use PC through USB, RS232 or GPRS remote adjusting and monitoring.Its compact structure, simple connection, high reliability, can be widely used in various types of generating set automation system, can also be used for fire pump, air compressor of automation control system.

Development background

Due to the power supply strain, often limited electric switch, power line fault, power grid maintenance etc, all can cause the mains power failure.The mobile base stations distributed in city countryside, in order to ensure the communication signal coverage, and using small steam generator (diesel) oil emergency power, to ensure the normal operation of the base station.In the process of frequent power, seemingly simple power emergency rescue process, it contains a lot of problems to be solved

After the base station blackout, if electricity personnel power, not in time will cause the battery discharge to the limit and the base station to base station equipment suit back.Multiple depth of battery discharge will seriously affect the service life of the battery.Especially in the case of blackouts, how to utilize the limited resource of oil machine to ensure emergency scheduling effectively reduced base station take over back.It is particularly important to improve base station interrupt indicators for operators.

By generating frequent, the need when power on power generation.Generate a lot of the cost of generating electricity, including vehicle cost, artificial cost, fuel cost.In the current management mode, the artificial cheating is often happened. False power. People switch, light power, bring many difficulties to the management of power generation.With rising fuel prices and artificial cost, base station maintenance costs rising sharply.Control power generation costs become a prominent problem in power management.

After the base station blackout, if electricity personnel power, not in time will cause the battery discharge to the limit and the base station to base station equipment suit back.Multiple depth of battery discharge will seriously affect the service life of the battery.Especially in the case of blackouts, how to utilize the limited resource of oil machine to ensure emergency scheduling effectively reduced base station take over back.Ascending base station interrupt indicators for operators is particularly heavy

Product features

Using three different WIFI connection, unlimited Internet presence, unlimited geographic borders, any places and conditions can achieve data transmission, realize the remote fault diagnosis and fault early warning, health check

The first kind of connection mode: in the application environment itself with wi-fi networks, cloud controller directly connected to the WIFI network, WIFI network between generator and cloud servers to establish real-time communication pipeline, real-time remote monitoring and control.

The second mode of connection: no WIFI in the application environment, but has a mobile phone networks, via mobile phone share the WIFI, also realize real-time remote monitoring, but usually for more for health inspection and remote fault diagnosis

The third kind of mode of connection: no WIFI in the application environment, no mobile phones network, through the APP to save the cloud controller of 7 kinds of data (can run 24 hours to save half a year) to save to the handset, until the phone to have WIFI or Internet environment, and will save the data to the cloud server, realize the remote fault diagnosis and fault early warning, early health check

The Black box patent technology

When monitoring the fault occurs, the fault time immediately before and after a period of time the data storage, and packaging them to cloud server, realize the black box recording function.Customers can use a mobile phone or PC terminal server access through these data, reproduce the fault, provides professional and highly effective for remote fault diagnosis

Power generation logging (tower power important basis)

To store and report of each record of generating, contains the boot time, downtime, generating time, generating electricity.Can record recently 6000 power.Allows the server and mobile phones, to read the past record of generating.Cloud system statistical power record, as an effective basis for power generation cost accounting.

History function (the working performance of the generator important basis)

To real-time operation of the generator data storage and reporting, including the sensor data, input state, the relay status, the engine data, power generation and load data and fault data, etc., can record 580 hours of recent history data.Allows the server and mobile phones, to read the history of past data.Cloud generator operation system analysis, the assessment of the generator current performance situation

Generator based on performance

Excitation voltage detection and warning

Judgment and early warning system for real-time detection, excitation voltage to report.Is one of the important means of analysis of generator performance

The actuator voltage detection and warning

Real-time detection of actuator voltage, warning judgment and report.Is one of the important means of analysis of generator performance

To reduce power between DaiWei last check time and improve the overall efficiency.

To strengthen the management of the power generation process, put an end to any length, human like now, such as a switch, light power base station maintenance cost.

Improves the power dispatching management, especially the security emergency power generation scheduling, balanced entire network at the same time of oil machine utilization to improve base station blackout support capability, protection interruption of base station.

Strengthen the generator maintenance management, reduce the generator of the scrap rate.

The cost of power generation management more scientific and more reasonable.
